this butterfly fish is about 2'' when i had him in quarantine tank, all he would eat is live brine shrimp, anything frozen he would ignore. after quarantine, i put him into my 60g frag tank. its established tank with bunch of pods/worms/aiptasia. observing this fish, every 3-4 minutes he will find something in a tank to eat. he wont touch aiptasia yet, but I did see him going after baby bristle worms and pods. there is no other fish in a tank that will compete for same food. is that enough nutrients for one to survive?
